Programmable clock generators simplify system design

Norwood, Mass.—Analog Devices Inc. (ADI) has introduced a pair of clock-generation and distribution ICs, featuring device integration, low-noise, low-jitter performance and signal output flexibility.

The AD9520 and AD9522 multi-output clock generators include a 512-byte embedded EEPROM memory block, affording system engineers a programmable clock product that can serve as both the source and system clock.

By programming their own specific set of output conditions using the on-chip memory, designers can easily configure the AD9520/2 as the source clock to ensure initial processing functions are synchronized when the system is powered on or reset. Competing clock ICs require a separate source clock, which must be independently matched to the system processor or microcontroller in order to program the system clock chip, adding component count, cost and complexity to network line cards, wireless and broadband infrastructure, medical imaging, and data converter clocking designs.

Pricing: $12.65 per unit in 1,000-unit quantities.
Availability: The AD9520 is available now in production quantities. The AD9522 is available for sampling and will be released in October.
